Stoogiometry: A Cognitive Approach to Teaching StoichiometryCarla R. KriegerMoe's Mall is a locational device designed to be used by learners as a simple algorithm for solving mole-based exercises efficiently and accurately. The mall functions as a map for setting up solutions to mole-based exercises using dimensional analysis. It clears the cognitive decks of students' easily overburdened short-term memory space, allowing them to focus on the versatility of the mole, rather than stepwise solutions to meaningless exercises. Krieger, Carla R. J. Chem. Educ.1997, 74, 306.

Those Baffling SubscriptsArthur W. Friedel and David P. MaloneyStudy of the difficulties students have in interpreting subscripts correctly and distinguishing atoms from molecules when answering questions and solving problems.Friedel, Arthur W.; Maloney, David P. J. Chem. Educ.1995, 72, 899.

A mole of M&M's Merlo, Carmela; Turner, Kathleen E.Engaging students by asking the question: How thick would the layer of M&M candies be if we covered the continental United States with a mole of these candies? Compare this to a mole of water.Merlo, Carmela; Turner, Kathleen E. J. Chem. Educ.1993, 70, 453.

Measuring Avogadro's number on the overhead projector Solomon, Sally; Hur, ChinhyuA Petri dish filled with water and stearic acid dissolved in petroleum ether upon an overhead projector can be used to introduce the topic of Avogadro's number.Solomon, Sally; Hur, Chinhyu J. Chem. Educ.1993, 70, 252.

An aqueous problem with an interesting solutionThomas, Nicholas C.Flow diagram outlining the steps to calculating the number of water molecules in one drop of water and the length of all these molecules stretched end to end.Thomas, Nicholas C. J. Chem. Educ.1987, 64, 611.

Teaching stoichiometry Steiner, Richard P.This author targets some of the reasons behind why it is so difficult for beginning chemistry students to understand stoichiometry. He reveals that if taught correctly and effectively, a 7-year old can grasp the concepts of stoichiometry.Steiner, Richard P. J. Chem. Educ.1986, 63, 1048.

An approximate determination of Avogadro's constantSzll, Thomas; Dennis, David; Jouas, Jean-Pierre; Wong, MabelAn experiment to determine a value for Avogadro's number by determining the relationship between the number of electrons flowing through an acidified solution of water and the number of moles of electrons which reduce hydrogen ions to produce hydrogen gas.Szll, Thomas; Dennis, David; Jouas, Jean-Pierre; Wong, Mabel J. Chem. Educ.1980, 57, 735.

Avogadro's number from the volume of a monolayerMoynihan, Cornelius T.; Goldwhite, HaroldThis article comments on and makes suggestions regarding the conduct of and treatment of data in the popular experiment in which Avogadro's number is estimated from the volume of a monolayer on a water surface.Moynihan, Cornelius T.; Goldwhite, Harold J. Chem. Educ.1969, 46, 779.

Chemical queries. Especially for introductory chemistry teachersYoung, J. A.; Malik, J. G.; Bolte, John(1) Is the mole a number or a weight? (2) Is there an easy way to locate a compound by volume and page in Beilstein? (3) What are the stages evident in a gas discharge tube as the pressure of the gas and the voltage are changed? - answer by BolteYoung, J. A.; Malik, J. G.; Bolte, John J. Chem. Educ.1968, 45, 718.

The MKS temperature scaleGeorgian, John C.A temperature scale to fit into the MKS system of units is proposed.Georgian, John C. J. Chem. Educ.1966, 43, 414.

Determination of Avogadro's number by Perrin's lawSlabaugh, W. H.The experimental procedure for determining Avogadro's number by the Perrin method includes preparing a monodisperse colloid, ascertaining the mass of the particles, and making an accurate count of the number of particles at two points in the equilibrated colloid.Slabaugh, W. H. J. Chem. Educ.1965, 42, 471.

The carbon-12 scale of atomic massesLabbauf, AbbasExamines the concept of atomic weight and the rise and coexistence of the oxygen and carbon scales of atomic mass.Labbauf, Abbas J. Chem. Educ.1962, 39, 282.

Gram equivalent weightsMeldrum, William B.The purpose of this paper is to review briefly the subject of equivalent weights and the more directly applicable gram equivalents and to offer a general method by which they may be deduced from chemical equations.Meldrum, William B. J. Chem. Educ.1955, 32, 48.

Letters to the editorStanden, AnthonyHelping students to understand the experiment they have done is a difficult task; experiments that claim to "prove" physical laws or determine Avogadro's number compound this problem.Standen, Anthony J. Chem. Educ.1954, 31, 46.
